Compiled: 2026-05-11 (retroactive synthesis of all trading sessions) Problem Class: Any capital allocation question — FX, crypto, CFDs, poker, casino. Pre-trade safety, position sizing, post-trade analytics. Axiom: "In non-ergodic systems, the strategy that maximizes EV is the one most likely to kill you. Survival > Optimization."

Full Kelly: f* = (bp − q) / b
Half-Kelly: f = f* / 2
Where:
b = net odds (reward ÷ risk)
p = probability of winning
q = 1 − p
Example (10% EV, 1:3 R:R):
b = 3, p = 0.55, q = 0.45
f* = (3 × 0.55 − 0.45) / 3 = 0.40 (40% — suicidal)
f = 0.40 / 2 = 0.20 (20% — still aggressive)
Practical: Cap at 1-2% risk per trade for operational safety.
Rule: Half-Kelly is the MAXIMUM. Industry standard 1-2% risk per trade is the operational floor.
| Arena | Variance Shield | Rationale |
|---|---|---|
| FX / CFD Trading | 2% max risk per trade | Ensures >95% survival over 100-trade sequences |
| Poker (Spins) | 300 buy-ins minimum | Neutralizes high-variance format |
| Poker (Cash) | 40 buy-ins minimum | Lower variance, faster recovery |
| Casino (Arbitrage) | 309-unit bankroll | Points farming protocol |
| Law | Rule | Source |
|---|---|---|
| No Weekend Holding | Close ALL positions before market close Friday | CS-d11d5a7c: Weekend gaps = unhedgeable ruin |
| No Martingale | Never double down after a loss | CS-459: Martingale = guaranteed ruin at N→∞ |
| Commission Awareness | Calculate REAL EV after all friction | CS-9a7c4607: 46% commission drag on FX → pivot to 0-commission oil |
| Drop-Down Trigger | If bankroll hits X% drawdown, mechanically drop stakes | CS-76208648: Eliminate psychological tilt |
| No FOMO Re-entry | If stopped out, wait for fresh setup | TRD-369: "Fuck-Unfuck" principle |
For mean-reversion and grid-based entries:
Layer 1: 30% of intended position at first signal
Layer 2: 30% at confirmation (e.g., structure break)
Layer 3: 40% at optimal entry (e.g., liquidity sweep)
Total risk across all layers: Still ≤ 2% of capital
| "Efficient" (Looks Smart, Kills You) | "Robust" (Looks Dumb, Survives) |
|---|---|
| Full Kelly sizing | Half-Kelly |
| 58% allocation, max profit | 6% allocation, survives tail |
| Narrow SL + High R:R | Wide SL + High WR |
| Hold for "the big move" | Partial profit + re-entry |
Rule: Growth = Edge − (Variance² / 2). Variance is a SUBTRACTION term. High WR structurally dominates High RR (TRD-367).

| Failure | Mitigation |
|---|---|
| FOMO Override | Gate 1 is NON-NEGOTIABLE. No "just this once." |
| Revenge Trading | Drop-Down Trigger is MECHANICAL, not discretionary |
| Weekend Gap Risk | Hard rule: Close ALL by Friday COB. No exceptions. |
| Commission Blindness | Calculate friction FIRST, then decide if edge survives |
